ABSTRACT
Objectives: The aim of this in vitro study was to evaluate the effects of polishing and aging on the surface properties of different restorative materials used in the posterior region.
Materials and Methods: In this study, a total of 576 samples were prepared by using 6 different composite resin (Filtek Z250-Z250, Filtek One Bulk Fill-FOB, Sonic Fill 2-SFB, Zenit Nano Ceramic-ZNC, Gradia Plus Indirekt-GPI, Estelite Bulk Fill Flow-EBF), a giomer composite resin (Beautifil Flow Plus-BFP) a glass ionomer cement (Equia Forte HT Fil -EQF) and a hybrid ceramic (Vita Enamic-VE). Sixty-four cylindrical specimens (8 mm diameter and 2 mm thickness) were prepared for each restorative material. The specimens were divided into two groups according to whether or not polishing was applied and further solution subgroups (n= 8). Surface roughness of the samples were measured with a contact-type profilometer before and after immersed in different solutions and thermal aging, and average roughness values were recorded. Statistical analysis was performed using the three-way analysis of variance test (p<0.05).
Results: It was determined that the material type, polishing method and immersing solution had a significant effect on the roughness change (p<0.05). Among the restorative materials, the highest roughness change (ΔRa) was found in Equia Forte HT, the lowest ΔRa value was found in EBF, GPI and Z250 groups (p<0.05). The highest roughness change was caused by cola and the lowest roughness change was observed in distilled water groups (p<0.05).
Conclusions: It was determined that the type of restorative material, polishing and aging and immersion solution had a significant effect on the roughness change.

Amaç: Bu çalışmanın amacı posterior bölgede kullanılan farklı restoratif materyallerin yüzey özelliklerine farklı polisaj sistemleri ve yaşlandırmanın etkisinin in vitro olarak değerlendirilmesidir.
Gereç ve Yöntemler: Bu çalışmada 6 farklı kompozit (Filtek Z250-Z250, Filtek One Bulk Fill-FOB, Sonic Fill 2-SFB, Zenit Nano Seramik-ZNC, Gradia Plus İndirekt-GPİ, Estelite Bulk Fill Flow-EBF), 2 farklı cam iyonomer siman (Equia Forte HT Fil -EQF, Beautifil Flow Plus-BFP), 1 hibrit seramik (Vita Enamic-VE) kullanılarak toplamda 576 adet örnek hazırlandı (n=8). Her bir restoratif materyalden 64 adet silindirik örnek elde edildi (çap: 8mm, kalınlık: 2mm). Örnekler 2 farklı polisaj yöntemi (Matris Bandı-MB, Kerr Occlubrush-KOB) ve sonrasında 4 farklı yaşlandırma solüsyonuna (distile su, kola, vişne suyu, soğuk çay) göre alt gruplara ayrıldı. Örneklerin yüzey pürüzlülüğü ölçümleri, farklı solüsyonlarda ve termalsiklusta bekletme öncesinde ve sonrasında profilometre cihazı ile yapıldı ve ortalama pürüzlülük değerleri kaydedildi. Çalışma sonucunda elde edilen verilerin istatistiksel analizi Dört Yönlü-ANOVA ile yapıldı.
Bulgular: Materyal türü, polisaj yöntemi ve bekleme solüsyonunun pürüzlülük değişiminde anlamlı etkisi olduğu belirlendi (p<0,05). Restoratif materyaller arasında en yüksek pürüzlülük değişimi (ΔRa) Equia Forte HT'de, en düşük ΔRa değeri ise Estelite Bulk Fill, Gradia Plus İndirect ve Filtek Z250 gruplarında görüldü (p<0,05). İçecek grupları değerlendirildiğinde ise pürüzlülük değişimine en fazla kola, en az ise distile suyun neden olduğu görüldü (p<0,05).
Sonuçlar: Bu çalışmanın sonucunda restoratif materyallerin yüzey pürüzlülüğünü; restoratif materyalin cinsi, kullanılan polisaj yöntemleri ve asitli içeceklerin etkileyebileceği belirlendi.
